COAL-POCKET.

SPECIFICATION forming part of Letters Patent No. 622,018, dated March28, 1899.

Application'filed January 28,

To all whom, t may concern:

Be it known that 1, DIGHTON A. ROBINSON, of the city of Minneapolis,county of Hennepin, State of Minnesota, have invented certain new anduseful Improvements in Coal- Pockets, of which the following is aspecification.

This invention relates to improvements in pockets designed especiallyfor handling coal, though applicable for handling other material, suchas ore or any kind of grain; and this invention is designed especiallyto cover certain improvements ou the coal-pocket shown and described inthe application of John Simpson, Serial No. 652,417, led September 21,1897.

In the drawings, Figure 1 is a side elevation of a coal-pocket embodyingmy invention, the pocket being represented in full lines asin itsdrawn-back or retracted position and its forward position beingpartially indicated by dotted lines. Fig. 2 is a side elevation,partially broken away, showing thel hopper in its forward positionandshowing the-eX- tension turned down and the dooropen. Fig. 3 is aperspective view of the 'combined lock and brake. l

In the drawings, 2 represents the body of the pocket, provided withsuitable wheels 3 and 5 and supported upon suitable tracks, (indicatedin the drawings by the dotted lines-7 and 9.) The manner of supportingthe pocket and its mode of operation and general construction is thesame as that of the pocket shown and described in said application ofJohn Simpson.

For the purpose of conducting the coal to any desired distance from theend of the pocket and at the same time 'forming a reliable andVconvenient means for securing the door of the pocket vI provide at theforward end of the pocket a trough-shaped apron or eX- tension 10,pivotally supported on the pocket by means of a suitable pivot 11, onepreferably arranged at each side of the pocket. This extension isadapted to be turned down into the position shown in Fig. 2, in which itforms an extension for the bottom of the pocket and conducts the coalfrom the pocket a distance equal to the length of the extension. Ledges13 are provided at the inner end of the eX- tension, and these when theextension is 1898. serrano. 888,818. cromati.)

turned down into the position shown in Fig. 2 strike against the angeMat the front end of the pocket. A sliding bolt 15 is provided upon theouter surface of the extension, and when the extension is turned np intothe position shown in Fig. 1 this bolt engages a recessed lug 16 uponthe front of the door 17, thereby locking the extension and the door andfirmly securing the same into position. A cord 1S is connected to thebolt 15, and by means of this cord the fireman or attendant can releasethe bolt 15 and turn the extension outward from the position shown inFig. 1 to the position shown in Fig. 2, although when the` pocket hasbeen brought into the position shown in Fig. 2 and the bolt 15 isreleased the weight of the coal in the pocket will ordinarilyautomatically turn the extension down into the position shown in Fig. 2.

I also prefer to provide a transverse partition 19, preferablyhingedupon a transverse rod 20, passing through the pocket and provided at itslower end with a flange 21, adapted to rest against the bottom of thepocket when the partition is in an upright position. A rod 22 extendstransversely beneath the pocket and is mounted in suitable bearings, inwhich it is capable of rotating. It is provided with an operating leveror handle 23 and has one or more lugs 24.-, adapted to extend throughslots in the bottom of the pocket and to engage the Flange 21 on thelower end of the partition 19. When the parts are in the position shownin Fig. 2, the partition will be locked, and only so much of the coal asis in front of the partition can escape from the pocket. When it isdesired to release the coal in the .rear of the partition, the lever orhandle 23 may be raised', thereby depressing the lug 24 and bringing itout of contact with the iiange 21. This will release the partition 19,and the coal will then fall by gravity under the partition.

I may useone or more of the partitions, if preferred, and may arrangesuch partition or partitions at any desired point or points in thepocket.

I also provide means for locking the pocket when it is drawn back orstanding in the position indicated by full lines in Fig. 1, and I alsoprovide a brake device by which the pocket maybe stopped or held at anydesired IOO point in its travel. A suitable beam or support 25 isarranged at a point near the rear end of the bucket, and suitablebearings 2o' are provided thereon. A shaft 27 is mounted in thesebearings, and it is provided at one end with a crank-arm 2S, havingthereon a suitable weight 29. A cord 30 is connected to this crank-armand extends to any convenient point, where it may be used by theliremanor attendant for the purpose of releasing the pocket. The shaft27 is provided with a ilattened portion 3l, having a transverse hole 32extending through it, and above this hole is a hook or dog 33. A rod 34is pivoted to the rear end of the pocket and extends through the opening32 and is provided at its end with a suitable collar 35. This rod isalso provided with a lug or shoulder 36, that is in position to beengaged bythe hook or dog 33 when the pocket is drawn back or stands inthe position shown in Fig. l. Vhen this hook is thus in engagement withthe proj eetion or shoulder on lthe rod 3l, the pocket is locked inposition and cannot move forward until the hook is released from saidlug. This is done by raising the crank-arm 2S and turning the shaft 27 asufficient distance to bring the hook out of Contact with the lug 3G.The pocket will then run forward; but it may be stopped at any point inits travel by releasing the crank-arm 2S, which causes the wall of theopening to grip the surface of the rod 34 with suiiieient force to holdthe pocket at any point in its travel. This device may also be used forregulating the speed at which the pocket will move forward.

As a safety device I also prefer to provide a chain 39, connected to therear end of the hopper and to a suitable beam or support 40, as shown inFig. l. This chain will act as a stop and prevent the pocket fromrunning too far forward.

It will be understood that the form and mode of construction of thevarious parts may be modified in many ways without departing from myinvention7 and I therefore do not limit myself to the details ofconstruction herein shown and described.

\Vhile the pocket herein shown and dcscribed is especially adaptedforhandling coal, and particularly for eoaling locomotives, Ido notlimit myself to its use for any particular purpose, as it mayobviouslybe used for loading coal or other material into ears or intovessels or any other receptacle.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The combination, with the movable pocket, of the rodpivotally connected t0 the rear end of said pocket, and the rotatablebrake-shaft through which said rod passes, for the purpose set forth.

2. rlhe combination, with the movable pocket, of the rod pivotallyconnected to the rear end of said pocket, and the pivoted hooi; or dogarranged to engagea lugor projection upon said rod when the pocket is inits retracted position, for the purpose set forth.

The combination, with the movable pocket, of the rod pivotally connectedthereto, the transverse rocking shaft, the weighted arm connectedtherewith, said shaft being provided with an openin g through which saidrod passes, for the purpose set forth.

4. The combination, with the movable pocket, provided With the rodpivotally con nected thereto and having a suitable lug or projection 3Gthereon, of the laterally-arranged shaft 27 provided with the opening32, the hook 33, the crank-armvQS, and the weight 29, said rod beingarranged to pass through the opening in said shaft and the hook 33 beingadapted to engage the lug 3G when the pocket is in its retractedposition, for the purpose set forth.

In testimony whereof I have hereunto set my hand this 24th day ofJanuary, 1398.

DIGHTON A. ROBINSON.
